超浓缩洗衣液是洗涤用品市场发展的重要方向。传统阴离子表面活性剂月桂醇醚硫酸酯盐、直链烷基苯磺酸盐和非离子表面活性剂天然月桂醇聚氧乙烯醚等原料因为溶解度低、容易凝胶等缺点很难满足超浓缩洗衣液的配方需求。异构醇醚非离子表面活性剂的倾点低,溶解速度快,润湿力强,泡沫低、易漂洗,而且与阴离子表面活性剂的配方相容性好,易配制超浓缩洗衣液。 相似文献

Nowadays laundry detergents are becoming increasingly popular as they can be metered automatically into the washing machine, impart softness, antistaticness, resiliency to fabrics, mild to eyes and skins and shows good dispersibility in water. Because it is consumed when it is used, the sale of laundry detergent is a rather large business. There are many different kinds or brands of laundry detergent sold, many of them claiming some special qualities as selling points. A Laundry detergent composition is a formulated mixture of raw materials that can be classified into different types based on their properties and function in the final product. The different classes of raw materials are surfactants, builders, bleaching agents, enzymes, and minors which remove dirt, stain, and soil from surfaces or textiles gave them pleasant feel and odour. The physico-chemical properties of surfactants make them suitable for laundry purposes. Laundry detergent has traditionally been a powdered or granular solid, but the use of liquid laundry detergents has gradually increased over the years, and these days use of liquid detergent equals or even exceeds use of solid detergent. This review paper describes the history, composition, types, mechanism, consumption, environmental effects and consumption of laundry detergents. 相似文献

The decade of the seventies saw dramatic changes in the formulation of heavy duty laundry detergents. The reduction in the
STPP content in laundry product formulations was a notable example. During the early 1970s, heavy duty liquid laundry detergents
were introduced and today represent an estimated 20% of the heavy duty laundry detergent market. A significant trend during
this decade toward lower wash temperatures also appeared. These developments in home laundry products and washing trends have
been followed by collateral developments in detergent enzyme technology. During the 1970s, a new generation of high alkaline,
active detergent enzymes were developed. This new group of alkaline proteases were characterized by greater activity and stability
under conditions of alkalinity between pH 10.5 to near 12, thus favoring phosphate-free detergent formulations. These enzymes
also were found to exhibit superior stability in nonbuilt liquid laundry detergent systems. Safety considerations at the plant
operation level have resulted in a continual improvement in the quality of coated and encapsulated detergent enzyme granulates.
During the past 10 years, detergent enzymes have passed through three generations of physical forms, from the powders to prills
to encapsulates. The decade of the 1980s offers exciting possibilities for enzymatic laundry products. The trend toward lower
wash temperatures, caused initially by the popularity of synthetic fabrics, is being compounded by a radical reappraisal of
household energy consumption patterns. In this new atmosphere of energy conservation, detergent enzymes will offer energy-saving
options in an assortment of laundry products. Finally, as we start this decade of the 1980s, the spiralling cost of petrochemical
feedstocks will cause us to rethink laundry product formulations and here again, detergent enzymes offer an important alternative
for the future. 相似文献
